ProMariner ProIso Charge 130 0 Voltage Loss Isolator 2 Alternator 4 Batteries

Meet the ProMariner ProIsoCharge130 Zero Volt Loss Isolator — the smart, digital way to manage power on board. Designed for 12V systems with two alternators and four battery banks, this advanced isolator delivers the full output of your engine alternators while eliminating the voltage loss that traditional diode-based solutions cause. More efficient charging, healthier batteries, and real-time visibility mean more time enjoying the water.

• Zero volt loss technology eliminates the typical 0.6V drop found in diode-based isolators, delivering faster, more efficient charging to all connected batteries.
• Intelligent Isolation and Charging Software prioritizes charging to a battery bank under load (house/inverter) while protecting engine start batteries, ensuring optimal power distribution when you need it most.
• Ignition Controlled Distributed On Demand battery management activates with ignition power on, preserving battery health when the boat is not in use.
• Real-Time LED Status Indicators provide at-a-glance health and charging information, with fault alerts for high/low output and voltage conditions across banks.
• Advance Regulator Ready remote sense connection enables precise control for advanced regulators, maximizing performance across the charging circuit.
• Easy Installation Modular design with included terminal stud insulator boots and a protective snap-on safety cover for quick, secure setup.
• IP66 Waterproof and Ignition-Protected rugged construction built to endure harsh marine environments while safeguarding your start and house batteries.
• Flexible Battery Bank Management isolates and charges up to four independent battery banks from a single alternator (model-specific); for dual engines, an exclusive 2-alternator input model supports up to four banks.
• Space-Saving, Diode-Free Solution eliminates bulky diodes and voltage-sensitive relays, freeing up space and simplifying wiring—while delivering reliable, balanced charging.
• Shore Power Ready when paired with ProNauticPSeries, you can enjoy seamless shore power charging and on-water reliability.
